The following teaser is from a post August 10, 2016 at Yahoo.com:
Paris (AFP) – The first people to reach the Americas could not have passed through the ice sheet-cleaving inland corridor long thought to be the entry point of humans to the continents, according to a study published Wednesday.
More likely, the New World pioneers of our species — probably some 15,000 years ago — inched along a Pacific coastline free enough of ice to support life-sustaining flora and fauna.
The exact route and timing of this maiden migration remains conjecture, the researchers said.
But what is certain, according to findings reported in the journal Nature, is that the textbook version of that passage is wrong.
